Problem 1 (10 pts) (a) A heat engine operates between a reservoir at 350°C, from which it absorbs 200 kJ of heat per cycle, and a reservoir at 0°C, to which it rejects 115 kJ of heat per cycle. Determine if this engine represents a reversible, irreversible, or impossible cycle? (4 pts) (b) An insulated container of capacity 2 m³ contains 10 kg of air. Work is done on the air till its pressure increases from 500 KPa to 1 MPa. Determine the change in entropy. Assume that specific heats evaluated at 300 K. (4 pts) (c) Find the maximum possible thermal efficiency for a heat engine operating between two reservoirs at 750°C and 27°C. (2 pts)
